Abstract (en)
An air maintenance tire assembly and a method of maintaining air within a tire is disclosed. The assembly comprises a tire having a tire cavity bounded by first and second sidewalls extending to a tire tread region; air pumping means for generating pressurized air for maintaining air pressure within the tire cavity at a preset pressure level, the tire having an elongate valve stem projecting outward from the tire cavity and having an internal valve stem air passageway in communication with the tire cavity and operative to direct pressurized air into the cavity; and a pressure regulator positioned opposite an inward end of the valve stem and operative to selectively open and close pressurized air flow from the valve stem internal passageway into the tire cavity.
